Evolution intumescent and acoustic sealant is a one part emulsion designed to resist the passage of both fire and sound.

In normal use, the sealant remains flexible enough to retain the sound reduction index of a structure. In the event of fire, it will intumesce and form a char, sealing the gap for up to 4 hours.
